The Mournful Duskywing (Erynnis tristis) occurs in the southwestern United States and Mexico. The two shots here were taken in Real Co., Texas, in May, 2003, with a Canon EOS 10D and EF 70-200mm F/2.8 L IS lens and 2X extender. There is a possibility that these two images are of a similar species known as Funereal Duskywing (E. funeralis), however, this is apparently difficult to establish from these images I have been told.
